FIELD: physics.
SUBSTANCE: invention relates to video encoding means. Decoder receiver receives a bit stream containing one or more layers of encoded images and a set of video parameters (VPS). Each layer, which is a flag (each_layer_is_an_ols_flag) of a set of output layers (OLS), is included in the VPS when all layers specified by the VPS are independently encoded without interlayer prediction, wherein each_layer_is_an_ols_flag indicates whether each OLS contains only one layer or at least one OLS contains more than one layer. Decode, by decoder processor, encoded image from OLS output layer based on each_layer_is_an_ols_flag in VPS to obtain decoded image. Decoded image is sent by the processor for display as part of the decoded video sequence.
EFFECT: high efficiency of video encoding.
